Advances in Online Monitoring for Pulp and Paper Wastewater Treatment Applications

Session 8  • Monday, November 2  •  4:45pm - 6:15pm


A growth pressure is defined as any factor affecting the microbial community and, as a result, overall treatment performance within a wastewater treatment system (WWTS). To evaluate, maintain, and/or increase the current performance of an aerated treatment system, it is critical to monitor all of the eight growth pressures – Biochemical Oxygen Demand (BOD) loading, pH, toxicity, aeration (dissolved oxygen), retention time, nutrients, biomass, and temperature.

Several different approaches have been utilized to assess these growth pressures and can provide enormous insight into the capabilities and shortcomings of a WWTS. The information obtained is essential in supporting defensible business decisions for operational and capital expenses, such as baffle installation or repair, dredging, additional aeration, nutrient optimization, and/or temperature control.

This presentation will provide an overview of advancements in continuous in-situ technology to monitor and evaluate system performance.
